Major touring art exhibitions are rarely the same from one venue to the next, for a variety of reasons. Lenders drop out, certain canvases can’t travel, or the available rooms in one museum are smaller than those in another.

Even in this context, there’s a dollop of overstatement in the Art Gallery of Ontario’s announcement that it will be the only Canadian stop for “a critically acclaimed solo exhibition from Tate Britain” of late paintings by J.M.W. Turner. The Tate show included more than 150 works; the AGO will show around 50.
